Me, today, trying to open my car door that has power locks.
A little background.  My car's power distribution is FUBAR'd and I am getting a new battery soon.  Because my power is screwed, my power locks are dodgy at best, so I haven't been locking my doors.  Today, while doing business downtown I felt the need to lock them.  Of course, when I returned they wouldn't open.  This happened before, and after persistent button pushing it opened. Not this time though.  So, as I was continuing to push the unlock button relentlessly, I called my wife to pass the time.  After talking with her for a minute or so she asked "does the key work in the door"?
My goodness, technology is ruining me.
